PHOTOS: 36 dead in fire at Oakland warehouse party

The fifth and perhaps final morning of recovery efforts dawned Wednesday with more than 90 percent of the rubble searched, and the cause of the catastrophic warehouse fire that has killed 36 people coming into focus. Authorities still have not given an official cause, and they bypassed their normal 6 a.m. press conference, as approximately one-third of the world and national media exited the scene. A woman from Lakewood is one of nine additional people identified by authorities as having died in last week's fire in Oakland. Friends and family of 21-year-old Vanessa Plotkin, who was attending UC Berkeley, had been posting on Facebook desperate pleas to locate the student.

The converted warehouse was known as the "Ghost Ship." Those who lived there or visited often say it was an artist workspace and illegal home for a rotating group of a dozen or more residents.
